Question

HCF of two positive integer a and b is c .if both the number a and b are tripled then the new HCF will be.​

Answer 1

HCF of a and b is given that it is c

Means both a and b are having a common factor c

Now if both a and b are get tripled

Then new common factor will be 3 and c

So new HCF will be 3c

Answer 2

The new HCF will be 3c.

Step-by-step explanation:

Given:

HCF of two positive integer a and b is c.

Both the number a and b are tripled.

To Find:

The new HCF.

Concept Used:

HCF ( Highest Common Factor) is the greatest number that divides each of the two or more numbers.

Solution:

As given,HCF of two positive integer a and b is c.

HCF ( Highest Common Factor)of two positive integer a and b =  c.

As given,Both the number a and b are tripled.

It means new value of both  positive integer  will be 3 a and 3 b.

HCF ( Highest Common Factor)of two positive integer 3a and 3 b = 3 c.

Thus,he new HCF will be 3c.
